Windows XP's Ping command-line utility helps verify IP connectivity to another computer or device on a TCP/IP network. When you issue the Ping command, it attempts to connect to the target device four times, and then it terminates.
In many troubleshooting situations, pinging the target device four times isn't enough. You may find yourself issuing the Ping command multiple times, which is time-consuming and frustrating.
However, the Ping command provides you with a parameter that configures the command to continuously ping the target device until you manually terminate the operation:
Ping -t xxx.xxx.xxx.xxx
In this command, xxx.xxx.xxx.xxx is the IP address of the target device.
To temporarily interrupt a continuous Ping operation and display the statistics, press [Ctrl][Break]. To completely terminate a Ping operation, press [Ctrl]C.
